        * expr.c (gfc_check_assign, gfc_check_pointer_assign): Emit error if
        the lvalue is a use associated procedure.

        * expr.c (gfc_check_pointer_assign): Emit error if lvalue and rvalue
        character lengths are not the same.  Use gfc_dep_compare_expr for the
        comparison.
        * gfortran.h: Add prototype for gfc_dep_compare_expr.
        * dependency.h: Remove prototype for gfc_dep_compare_expr.
